新航道剑桥雅思8作文：
参考范文 The diagram on the left illustrates the process by which cement is made whilst the diagram on the right shows us how concrete is made.
We can clearly see that the first stage in cement production is to put two substances – limestone and clay – through a crusher to create a powder. This powder then goes through a mixer and is then heated in a rotating heater. Once the powder has gone through the mixer and heater, it is ground and the cement is packed into bags.
The diagram on the right hand side tells us that concrete is a mixture of four ingredients in differing proportions. Cement makes up 15% of the mixture, water constitutes 10%, sand 25%, and gravel (i.e. small stones) 50%. These ingredients are mixed in a rotating concrete mixer to make concrete.
In summary, the production of cement and the production of concrete appear to be fairly simple processes.

左边的图描述的是水泥生产的流程,而右边的图则是混凝土生产的流程。
我们可以从图中清晰地看见水泥生产的个步骤是将石灰石和粘土放入破碎机中磨 成粉末。接着这些粉末进入到搅拌机里进行混合,然后在回转预热器中进行预热。粉末一旦 进入搅拌机和预热器,将被磨碎,水泥就此生产完成,之后便可以装入袋中。
从右边的图可以看出,混凝土是由四种原料按照不同的比例混合而成的,其中水泥占 15%,水占 10%,沙子占 25%,沙砾占(如小碎石)50%。这些原料在一个旋转的混凝土搅拌 机中混合而成混凝土。
总的来说,水泥和混凝土的生产流程看上去是相当简单的。
